python3 自动化部署javaweb系统到远程tomcat

最近刚刚学python，非想要做点东西不可。。。。

做了一个自动化部署的脚本，献丑了。

以下假设数据库与应用在一起

过程如下：

本地maven打包上传到服务器服务器数据库库备份服务器关闭tomcat服务器应用程序备份服务器清除应用、work服务器启动tomcat

/utils/SSHConnection.py ，远程操作工具类

#! /usr/bin/pythonimport osimport paramikoclass SSHConnection:    __hostname = ''    __port = 22    __username = ''    __password = ''    __ssh = ''    def __init__ (self, hostname, port, username, password):        self.__hostname = hostname        self.__port = port        self.__username = username        self.__password = password    def SSHClient(self):        print ( 'ssh %s@%s ....' % (self.__username, self.__hostname) )        try:            self.__ssh = paramiko.SSHClient()            self.__ssh.set_missing_host_key_policy( paramiko.AutoAddPolicy() )            self.__ssh.connect(hostname = self.__hostname, username = self.__username, port = self.__port, password = self.__password)            print ( 'ssh %s@%s success!!!' % (self.__username, self.__hostname) )        except Exception as e:            print ( 'ssh %s@%s: %s' % (self.__username, self.__hostname, e) )            os._exit(0)    def exec_command(self, command):                print ('command:', command)        stdin, stdout, stderr = self.__ssh.exec_command(command)        err_list = stderr.readlines()        if len( err_list ) > 0:            print ('ssh exec remote command [%s] error: %s' % (command, err_list[0]))        print (stdout.read().decode('utf-8'))    def upload(self, src, dst):        try:            sftp = self.__ssh.open_sftp()        except Exception as e:            print ('open sftp failed:', e)            os._exit(0)        try:            print ('uploading file: %s --> %s' % (src, dst))            sftp.put(src, dst)            print ('uploaded file: %s --> %s' % (src, dst))            sftp.close()        except Exception as e:            print ('uploading file failed:', e)            os._exit(0)    def close(self):        self.__ssh.close()
